The first American commercially built-and-operated crew spacecraft in eight years docked successfully Sunday at the International Space Station.

There was, however, no crew aboard the spacecraft, just a test dummy named Ripley, in a nod to the lead character in the Alien movies.

The docking was carried out autonomously by the Crew Dragon capsule, as the three astronauts on board the International Space Station watched.

The Space X Crew Dragon capsule lifted off atop a Falcon 9 rocket early Saturday from Florida’s Kennedy Space Center.

The Dragon brought supplies and test equipment to the space station where it will spend five days as astronauts conduct tests and inspect the Dragon’s cabin.

NASA has awarded millions of dollars to Space X and Boeing to design and operate a capsule to launch astronauts into orbit from American soil some time this year.

It is not immediately clear whether that goal will be reached.

Space X is entrepreneur Elon Musk’s company. Musk is also the CEO of electric carmaker Tesla.

Currently, America relies on Russia to launch astronauts to the space station.

Russia charges about $80 million per ticket.

Exercise and diet are keys to a healthier life, as many studies show, but a heart specialist also recommends something more.

“One, two, three — twirl.”

Kendra Martin is taking photographs of three little girls in chiffon dresses. As they twirl, Martin tells them to smile.

“All right, big smiles!”

“I tell people to fake laugh, and they feel stupid doing it, but the result is theyʼre laughing, and it turns into a genuine smile,” Martin said.

And, in this case a giggle.

Big grins and giggles pay off on camera. The girls may be too young to have heart problems, but the smiles can promote heart health.

Brain rewiring

Dr. Anand Chockalingam is a heart specialist at the University of Missouri Health Care who tells his patients to smile.

“When we smile, the brain wiring gets altered. The chemicals that are released are more positive,” he said.

Chockalingam’s advice is supported by a number of studies. He says smiling is a first step in fighting stress and its ill health effects.

When you feel stressed, your body releases a surge of hormones, including adrenaline and cortisol.

Adrenaline increases your heart rate and blood pressure. Cortisol, the primary stress hormone, increases sugars in the bloodstream. If you are truly in danger, these hormones can help, but too much of these stress hormones too frequently can lead to heart disease and stroke.

​Bad habits arise

People who are stressed look for ways to cope. The American Heart Association says smoking, overeating or drinking alcohol as a way to reduce the stress can harm your heart and other organs.

“Once people smile, they are relaxing,” Chockalingam said. “This relaxation directly lowers blood pressure, improves sugar levels in the blood.”

Chockalingam tells his patients to smile 20 times an hour. It might seem like a lot, but it doesn’t involve drugs or have any negative side effects.

“If we are smiling, we are breaking that link between stress and health,” he said.

Smiling is something Martin does to improve her photography.

“Waking up in the morning with a smile on my face, you know, itʼs gonna put everybody in a better mood,” she said.

And it provides a little boost to everyone’s heart health.

Striving to improve behavior at soccer matches, FIFA President Gianni Infantino sees women as role models for male players.

There is less simulation and time-wasting in the women’s game, according to Infantino, and it’s time for men to clean up their act to improve the image of soccer.

“The men’s game has developed incredibly, positively, but a few maybe side effects have unfortunately developed as well that we are fighting now,” Infantino said Saturday. “Let’s take the example of the women’s game.”

Infantino’s admiration for the conduct of female players stands in contrast to predecessor Sepp Blatter, who urged them to wear tighter kits to make the game more popular.

“Women are nicer than men, probably, generally,” Infantino said. “Sometimes we men feel that we need to show how strong we are, probably in the human nature, and this is reflected as well in some of the behavior in society in general but also on the football pitch.”

On field behavior

Infantino was speaking after the game’s lawmaking body, the International Football Association Board, discussed ways of improving on-field behavior at its annual meeting, including treatment of referees. Yellow and red cards for misconduct by team officials are now entered in the laws of the game after successful trials.

“When it comes to behavior,” Infantino said, “if there’s something to learn from the women’s game … it’s certainly this: This is much less time lost and wasted on simulations or on other situations we criticize in the men’s game. We are intervening now.”

Such as ensuring someone substituted “doesn’t greet all the players before going out (leaving the pitch) and so on — wasting time,” Infantino said. “All the things you don’t see in the women’s game.”

Diving has been reduced by the introduction of video review, Infantino said, while announcing his support for VAR at the June 7-July 7 Women’s World Cup in France. The decision will have to be ratified by the FIFA Council at a meeting in two weeks in Miami.

“Players now know that it’s not just sufficient to have a look where is the referee, so if he doesn’t see me I can simulate, because he or she will be caught,” Infantino said. “That’s why VAR automatically helps the fight against simulation and diving in a very efficient way.”

Handballs

To reduce controversies, the handball law has been adjusted.

Referees won’t necessarily have to decide if there was deliberate handling, but judge the outcome and whether an unfair advantage was obtained by gaining possession or control of the ball.

It won’t be an offense if the arm or hand is very close to the body but it will be if they are in an elevated position when the ball is handled. But even if a player accidentally handled while scoring, the goal would be ruled out.

Kicks and penalties

Disruptive behavior around free kicks should be reduced from June. The attacking team will not be allowed within 1 meter (yard) of the defensive wall in an attempt to stop players jostling and matches being delayed by the necessary intervention of referees.

In two changes affecting goalkeepers, goal kicks won’t have to leave the penalty area and only one foot will have to remain on the line when facing a penalty.

Substitutes

To speed up the game, players being substituted must leave the field at the nearest point rather than at the halfway line.

“It’s a fairly standard time-wasting tactic that when a manager wants to make a substitution, he can send a player to be substituted to the opposite end of the pitch,” said Scottish Football Association chief executive Ian Maxwell, one of the eight IFAB members.

FIFA has four delegates and the British nations have the other four, with six votes required for a change to the laws which come into effect from June.

America’s newest capsule for astronauts rocketed Saturday toward the International Space Station on a high-stakes test flight by SpaceX.

The only passenger was a life-size test dummy, named Ripley after the lead character in the “Alien” movies. SpaceX needs to nail the debut of its crew Dragon capsule before putting people on board later this year.

This latest, flashiest Dragon is on a fast track to reach the space station Sunday morning, just 27 hours after liftoff.

Five day round trip

It will spend five days docked to the orbiting outpost, before making a retro-style splashdown in the Atlantic next Friday — all vital training for the next space demo, possibly this summer, when two astronauts strap in.

“This is critically important … We’re on the precipice of launching American astronauts on American rockets from American soil again for the first time since the retirement of the space shuttles in 2011,” said NASA Administrator Jim Bridenstine. He got a special tour of the pad on the eve of launch, by SpaceX founder and chief executive Elon Musk.

An estimated 5,000 NASA and contractor employees, tourists and journalists gathered in the wee hours at Kennedy Space Center with the SpaceX launch team, as the Falcon 9 rocket blasted off before dawn from the same spot where Apollo moon rockets and space shuttles once soared. Across the country at SpaceX Mission Control in Hawthorne, California, company employees went wild, cheering every step of the way until the capsule successfully reached orbit.

Looking on from Kennedy’s Launch Control were the two NASA astronauts who will strap in as early as July for the second space demo, Doug Hurley and Bob Behnken. It’s been eight years since Hurley and three other astronauts flew the last space shuttle mission, and human launches from Florida ceased.

Private companies

NASA turned to private companies, SpaceX and Boeing, and has provided them $8 billion to build and operate crew capsules to ferry astronauts to and from the space station. Now Russian rockets are the only way to get astronauts to the 250-mile-high outpost. Soyuz tickets have skyrocketed over the years; NASA currently pays $82 million per seat.

Boeing aims to conduct the first test flight of its Starliner capsule in April, with astronauts on board possibly in August.

Bridenstine said he’s confident that astronauts will soar on a Dragon or Starliner, or both, by year’s end. But he stressed there’s no rush.

“We are not in a space race,” he said. “That race is over. We went to the moon and we won. It’s done. Now we’re in a position where we can take our time and make sure we get it right.”

Scientists estimate half of the world’s corals have been devastated as climate change has led to warmer oceans. When water temperatures get too high, corals become stressed and expel the algae that coats their tissues and provides the corals’ primary food source. The corals gradually lose their color, known as bleaching, and many of them die. But surprisingly, there are corals in one sea in the Middle East that are resistance to the rising temperatures. VOAs Deborah Block explains why.

The charity Doctors Without Borders has suspended its Ebola virus-fighting operations in the Democratic Republic of Congo after attacks on two of its treatment centers this week, raising the risk that Ebola infections in the area will increase.

The World Health Organization has called the Feb. 24 attack in Katwa and the Feb. 27 attack in Butembo “deplorable.” In Butembo, where the center housed 12 confirmed Ebola patients and 38 with suspected Ebola, four patients with the highly contagious virus fled for their lives. One is still missing.

The attackers set fire to the treatment centers and engaged in gunfire with security forces.

MSF halts treatment

Doctors Without Borders, also known as Medicins Sans Frontieres, or MSF, announced Friday it had halted treatment in Butembo, in the eastern RDC province of North Kivu. It had done the same earlier in the week in Katwa, the latest hot spot in the outbreak first reported last August.

WHO spokesperson Christian Lindmeier told reporters that experts must now track possible paths of infection.

“It is highly important to find those people, that last patient, and then, of course, immediately start the contact tracing and monitor the contacts these patients might have been in touch with,” Lindmeier said.

DRC health minister Oly Ilunga Kalenga told VOA French to Africa that the problem with the Ebola situation lies in Katwa and Butembo, where “communities are not fully engaged.” He also said armed groups and unidentified gunmen are common in the area.

A spokeswoman for DRC’s health ministry, Jessica Ilunga, said the government will examine options over the next few days to protect health agents and stop any spread of the disease resulting from the attacks.

Michel Yao, incident manager for the WHO, said of the attackers: “It looks like an organized group that wants to target treatment centers.” He said the loss is great because the centers that were damaged had been testing experimental treatments with some success.

Whitney Elmer of the group Mercy Corps told The New York Times that the loss of two treatment centers at the midst of the outbreak is “crippling.”

Hundreds with disease

The Health Ministry reported that at least 885 have contracted the disease, and 550 have died of it, since the outbreak began.

The Ebola outbreak in North Kivu and Ituri provinces, declared in August, is the second largest in history, after the 2014 epidemic in West Africa that killed more than 11,000 people. The WHO says the risk remains “very high” for the outbreak to spread across the borders into Rwanda, Uganda or South Sudan — or to spread nationally across the DRC.

NASA’s newest Mars lander has started digging into the red planet, but hit a few snags, scientists said Friday.

The German drilling instrument on the InSight lander hit what appeared to be a couple of stones. It only managed to burrow between half a foot (18 centimeters) and about 1-and-a-half feet (50 centimeters), far short of the first dig’s goal, said the German Aerospace Center.

The hammering device in the “mole” was developed by the Astronika engineering company in Poland.

“This is not very good news for me because although the hammer is proving itself … the Mars environment is not very favorable to us,” said the company’s chief engineer, Jerzy Grygorczuk.

Over time, the team is shooting for a depth of up to 16 feet (5 meters), which would set an otherworldly record. The lander is digging deep to measure the planet’s internal temperature.

InSight landed on Mars last November. Flight controllers at NASA’s Jet Propulsion Laboratory in California sent commands to the lander Thursday to begin digging. It’ll rest for a bit before burrowing again.

The spacecraft already has a seismometer on the surface, listening for potential quakes. The lander is stationary, but has a robot arm to maneuver these two main experiments.
